Description
본 발명은 화재를 비롯한 각종 재난발생시 각종 유독성 가스에 의한 질식을 방지하고 유독성 가스가 있는 사고장소에서 안전한 장소로 대피하는 동안에도 안전하게 호흡을 할 수 있도록 해 줄 수 있는 간이 공기재호흡기에 관한 것이다.The present invention relates to a simple air respirator that can prevent asphyxiation due to various toxic gases during a fire and other disasters and to allow a safe breathing while evacuating to a safe place in an accident place having toxic gases.
종래에 대한민국 실용신안 공고번호 제 1990-0001192 호로 알려진 바 있는 인명구조용 산소마스크는 마스크 전면에 부착된 기화기의 하단일측에 소형압축산소통을 설치하여 이 산소통으로 부터 공기를 공급 받을 수 있도록 된 것이었다.The lifesaving oxygen mask, which was previously known as Korean Utility Model Publication No. 1990-0001192, was designed to receive a small amount of compressed communication at the bottom side of the vaporizer attached to the front of the mask to receive air from the oxygen cylinder.
이와 같은 종래의 인명구조용 산소마스크는 산소통으로 부터 공급되는 한정된 공기를 들숨으로 하고, 날숨은 외부로 방출하는 것이므로 공급된 공기를 반복하여 사용할 수 없었기 때문에 사용시간이 매우 짧았었다.Such a life-saving oxygen mask in the prior art as a limited air supplied from the oxygen tank, the exhalation is discharged to the outside, so the supplied air was not used repeatedly because the use time was very short.
일반적으로 보통 성인의 경우 일분간에 12내지 24회 정도의 호흡수를 가지며 일회호흡량이 약 500mℓ정도이므로 종래의 인명구조용 산소마스크는 용량이 18ℓ정도인 소형압축산소통을 사용 할 경우 사용시간이 1분 30초 ~ 3분정도에 불과하므로 안전한 장소로 대피하는데 이 보다 많은 시간이 소요되는 지하철구내나 대형건물등과 같은 장소에서는 유효하게 사용할 수 없는 등의 문제점이 있었다.In general, adults have a breath rate of 12 to 24 times per minute, and a one-time breathing amount is about 500mℓ. Therefore, a conventional life-saving oxygen mask has a use time of 1 minute when using a compact compressed communication with a capacity of about 18ℓ. Because it is only 30 seconds to 3 minutes, evacuation to a safe place, there was a problem such as not being able to use effectively in places such as subway premises or large buildings that takes more time.
본 발명의 목적은 소형압축산소통으로부터 공기주머니에 공급되는 한정된 공기를 반복 사용하면서 서서히 소모할 수 있도록 함으로서 사용시간을 연장시켜 줄수 있는 간이 공기재호흡기를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a simple air rebreather that can extend the use time by gradually using the limited air supplied to the air bag from the compact compression communication.
본 발명의 다른 목적은 어두운 곳에서 사용자의 위치를 구난 작업자와 같은 다른 사람에게 쉽게 알려 줄 수 있고 사용자가 주변을 살펴 볼 수 있는 무전원 비상 신호수단을 가진 간이 공기재호흡기를 제공하는데 있다.Another object of the present invention is to provide a simple air respirator having a non-power emergency signal means that can easily inform the other person, such as a rescue worker in a dark place, the user can look around.
